Discordance:
It appears that the benign biopsy result does not match the "shadowing" on the imaging. This is a mismatch that we call discordance. I recommend you find a breast specialist in your area who can evaluate you and look over the images to provide an answer. Good luck

Depends:
Most of the time additional treatment is required. These tumors often have "roots" so to speak, and despite healing up, there is often residual skin cancer that will come back in a few months to years. Treatment at that time may not be as simple.
